Hoʻolauna

ʻO 2-Bromo-5-iodopyridine he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:

 

ʻAno maikaʻi:

ʻO 2-Bromo-5-iodopyridine he aniani ʻeleʻele paʻa, kala ʻole a māmā paha, paʻa i ka lumi wela a me ke kaomi.

 

Hoʻohana: Hiki ke hoʻohana ʻia ma ke ʻano he catalyst a he hana koʻikoʻi i nā hopena kūlohelohe. Hiki ke hoʻohana ʻia ka 2-Bromo-5-iodopyridine ma ke ʻano he ʻimi fluorescent no ka hoʻopaʻa ʻana a i ʻole ka ʻike ʻana i nā biomolecules.

 

Hanana:

ʻO ke ʻano o ka hoʻomākaukau ʻana o 2-bromo-5-iodopyridine he maʻalahi. ʻO ke ala maʻamau ka hana ʻana i ka 2-bromo-5-iodopyridine me kahi mea hoʻoheheʻe kūpono, e like me ka pane pololei me ka iodine i ka ether a i ʻole ethanol. Ma hope o ka hopena, hoʻomaʻemaʻe ʻia ka huahana e ka crystallization a i ʻole ka unuhi ʻana, a hiki ke hoʻomākaukau ʻia ka 2-bromo-5-iodopyridine.

 

ʻIke palekana:

I ka hoʻohana ʻana a i ʻole ka mālama ʻana i ka 2-bromo-5-iodopyridine, pono e hoʻomanaʻo ʻia kēia mau ʻōlelo palekana:

Hiki i ka 2-Bromo-5-iodopyridine ke hoʻonāukiuki i nā maka a me ka ʻili, e hoʻokomo i nā mīkina lima pale kūpono a me nā maka.

E hōʻalo i ka hoʻohuʻu ʻana i ka lepo o 2-bromo-5-iodopyridine a pono e hana ma kahi wahi hoʻoluʻu maikaʻi.

I ka hihia o ka ʻai ʻana a i ʻole ka ʻike ʻana i ka 2-bromo-5-iodopyridine, e ʻimi i ka lāʻau lapaʻau a i ʻole e nīnau koke i kahi loea.

I ka mālama ʻana i ka 2-bromo-5-iodopyridine, pono e mālama ʻia ma kahi maloʻo a maloʻo a pale i ka hoʻopili ʻana me nā mea oxidants a i ʻole nā ​​​​mea hiki ke ahi.
